HYDROVAPORIZER.

Application filed July 12, 1916. Serial No. 108,868.

To ZZ whom t may concern:

Be it known that I, EUGENE D. FERRELL, a citizen of the United `States,residing at lVayzata, in the county of Hennepin and State of Minnesota,have invented certain new and useful Improvements in Hydrovaporizers;and I do hereby declare the following to be a full, clear, andexact'description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same. A

My invention has for its object to provide an extremely simple andeflicient device :tor

introducing a spray of water into the explosion' chambers of inteinalcombustionA engines. This device, because of the func- 4 tion itperforms, I have called a hydrosystem o theengine,

vaporizer.

It is a well known fact that the introduction of water vapor with. theexplosive charge into the explosion chamber ofan explosive engineincreases the efficiency of the engine and assists lubrication. A deviceof' this kind will increase' the eiiiciency of an in* ternal 'combustionengine under almost all, or nearly all atmospheric conditions, but isespecially desirable when the air is hot and dry.

The improved hydrovaporizer, inits preferred form and arrangement, isillustrated in the accompanying drawings wherein like charactersindicate like parts throughout the `several views.

Referring to the drawingsz' Figure 1 is a side elevation showing thehydrovaporizer applied to an explosive engine of the well known Fordtype;

Fig. 2 is a side elevation of the hydrovaporizer;

Fig. 3 is a horizontal section on the line 3 3 of Fig. 2; and

Fig. 4 is a vertical section on the line 4.--4 of Fig. 3.

The Water jacketed cylinder casting of the engine is indicated, as anentirety, by the numeral 5. The numeral 6 indicates a hot water outlettube from the water jackets of the several cylinders. The numeral 7indicates the carbureter and the numeral 8 the manifold that leads fromthe carbureter to the explosion chambers of the several cylinders of theengine.

The water for supplying the water vapor may be taken from any suitablesource, but is taken from the water circulating preferabl so that therewill be a 13 lis adapted to be opened and closed, at'

will, by an oscillatory cubofvalve 14'provided at one end with an arm 15connected to an operating rod 16. This operating rod 16 extends througha guide tube 17 shown las supported at onel end directly fromy ahead 18that is detachably secured to the outer side of the chamber containingthe filtering material 10. The rod 16 will usually beex'- tended throughthe instrument board of the automobile, so that the valve 14 Amay be operated from the drivers seat.

The valve chamber 12, at its lower end, has an air intake port 19 thatis normally closed by a cheek valve 20, asshown, off the ball type.Screwed into the upper end .of the said valve seat 12 is a reducing tube21, the lower portion of which has a port 22 normally closed by a checkvalve 23, as shown,

`of the ball type. A small stem 24 connects the two check valves 20 and23 so that when the former Ais raised, the latter will also be raised.Normally, both of the said check p valves will be seated.

The -numerall 25 indicates a small Water supply pipe which leads fromthe water jacket of the cylinder castin perferably from the outlet tube6 thereotg, and is connected to the upper end of the reducing tube 21,by a suitable coupling 26, best shown in l praying of water requirescirculation of air 1n contact with the Water to'be sprayed, and this isprovided for in the device above described. When the cut-of valve 14 isclosed, there will, of course, be no supply of vapor. By openin the saidvalve 14, more or less quantity o vapor supplied may be regulated.

A fine meshed Ascreen 10a is placed in the filtering chamber adjacent toits delivery nipple dla This screen holds the ltering material in place,and it is of such ine mesh ico that water will not low therethrough bygravity but will be delivered therethrough in the form of a tine sprayunder the action of the suction produced from the engine.

Vhen the said valve 14 is opened, the water vaporizing action will be asfollows:

Under each suction stroke of the engine,

` and simultaneously with the intake of the waporizecl.

hydrocarbon'vapor from the carluireter, the suction produced in thevalve chamber 12, acting on the relatively large check valve 20, willsimultaneouslyraise the two valves 2O and 23, thereby simultaneouslyopening the air port 19 and water port Then the said p01 22 is opened,water will flow downwith the explosive charge; and when the eX- plosiontakes place in the engine, will be converted into steam, which, initself, not only assists in lubrication, but increases ineffective forceof the explosion, probably, in 3 several different ways, but certainlyto the extent that it tends to prolong the pressure impulses produced bythe explosion.

The device may be' cheaply constructed and easily applied to any and allexplosive 3 or internal combustion engines.

lVhat I claim is:

A hydrovaporizer for explosive engines .comprising a casingprovidedlwith a discharge port and having axially spaced air 4 and waterintake ports delivering the air and water, respectively, inward fromopposite directions, valves normally closing said air and water intakeports, said air valve having greater area than said water 4 valve, anaxial connection between said two valves whereby, under the action ofsuction on said air valve, both. valves will be positively andsimultaneously opened', and a cutofi' valve for simultaneously cuttingsaid air 5 and water valves out of action.

In testimony whereof I affix my signature in presence of two witnesses.

EUGENE D. FERRELL.
